# DeFi Protocol TVL Lookup

> DeFi Protocol TVL Lookup is a paid API for AI agents from defi-api.agenticfi.wtf, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-14).

Returns Total Value Locked (TVL) for the top 50 DeFi protocols or a specific protocol with per-chain breakdown

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability defi-api-agenticfi-wtf-bc18b38b
```

Example prompt: What's the current TVL for Aave broken down by chain, and also show me the top 50 DeFi protocols by total value locked?

## When to prefer this

Use this endpoint when you need current TVL figures for specific DeFi protocols or want a ranked overview of the top 50 protocols. Ideal for comparing protocol size, tracking TVL trends, or performing chain-level TVL analysis. Prefer this over lending-rate endpoints (the sibling endpoint) when the user cares about locked capital rather than interest rates.

## Known failure modes

- Unknown protocol slug returns empty or error response
- Payment of 0.001 USDC required per call via x402 — missing payment results in 402 error
- Invalid protocol slug (e.g. typo) returns no data
- Rate limiting if too many requests sent in quick succession

## How this service works

TVL by protocol - top 50 or specific protocol with chain breakdown

## Output

Returns TVL data either for a specific protocol with a per-chain breakdown of locked value, or a ranked list of the top 50 DeFi protocols by TVL if no protocol is specified.
